The horizontal {iange of the angle bar 28 is pivoted to a cross bar 34 parallel with-the rocker 14- and having a central pivot 35 in the platform 9. A substantially semi-circular band 36 is secured at its ends to the b ar 34. and is adapted t0 s'li'de in a guide '37 mounted on 'the underside 'of the 'platform 9 and said band l36 has a 'series of holes 38 therein at intervals adapted to re'ceive a lookingr pin 39. U'pon the removal 'of this pin 'the 'parallel me'r'nbers l14 and -34 may be swung forward 'or bekward, forming i`n eleet 'a parallel link motion 'ai Shi-fi 'the planer blade to the desired angle and move the lever operating mechanism of the planer blade a corresponding distance. The ends of the bar 34 project between the horizontal portions of the truss bars and angle bars 40 secured to the horizontal flanges of Said truss bars and have Treedon 'of horizontal movement therein to Jallow for the Convenient adji'lstnent of the planer blade.
